BRUSH MACHINEv Application March 13, 1936, Serial No. 68,683

26 Claims.

This invention relates to brush machines, and particularly machines of the type illustrated in my Letters Patent of the United States No. 1,654,655, dated January 3, 1928, wherein brush blocks arer bored and wisps of fiber or bristles are successively removed from a source of bristle supply and transferred to a station where each succeeding wisp is doubled on itself, seated in a hole of' a brush block, and therein fastened byV means of a wire staple that is formed by the machine and is associated with the wisp before their insertion in the brush block.

Referring to the drawings, 35 designates the main frame comprising a base 36, spaced parallel standards 31 rising therefrom, and a horizontal beam 38 connecting the upper ends of the standards. The main shaft 39 is journaled in bearings in rearwardly extending brackets 390 supported by the beam 38, which shaft has loose thereon a positively driven pulley 40 adapted to be clutched to or unclutched from the shaft and other elements mounted thereon as will presently appear.

4| designates a lower transverse shaft which is journaled in bearings on a pair of spaced armsl 42 extending rearwardly from a cross-bar 43 bolted to the standards 31 of the main frame. The shaft 4l, which is intermittently driven through suitable connections with the main shaft;

has fast thereon spaced apart wheels 44 and 45 to the former of which are affixed segmental pattern cams 46 and 41 and to the latter of which wheels are secured pattern cams 48. These cams determine the succeeding movements of the mechanism for controlling the various operative positions of the block supporting tables 49 and 50 in respect to boring and tuft inserting'devices as" hereinafter described.

In the present instance the shaft 4| has fast thereon a spur wheel 5l in mesh with a pinion 52 fast on a short shaft 53 having its bearings in a suitably-disposed bracket 54 on the cross-bar 43. Fast on the shaft 53 is a ratchet wheel 55 with the teeth of which engages a pawl 56 on a rockarm 51 loose on the shaft 53. This arm is pivotally connected by means of a rod.58 with the arm 59 of a bell-crank which is fulcrumed on a bracket 6U at the frame beam 33. The other arm 5| of the bell crank has a roll 62 which is held by means of a suitably disposed spring 63 in operative contact with a cam 64 normally loose on the main shaft, which cam can be clutched at will to the power driven pulley 48 loose on the main shaft and which cam can also be automatically released from the pulley at predetermined intervals. (See Figs. 2, 4 and 5.) The contour of the cam 64 issuch that when it is clutched to and driven by the pulley the bell crank is rapidly oscillated and intermittent rotary motion thereby transmitted to the shaft 53 through the link and pawl and ratchet connections, thence through the pinion and spur wheel to the shaft and the pattern wheels. To prevent the overrunning of the pattern cams 46, 41 and 48 in their intermittent rotation, the shaft 53 is provided with a brake drum 65 embraced by brake arms 66.

The means for clutching the cam 64 to and releasing it from the pulley 43 is of the character disclosed in my prior Patent No. 1,654,555 and therefore it requires no detailed description herein. Suice itto say that such means includes amanually operative crank shaft 51 for actuating brake and clutch mechanism 68 in relation to the cam and the pulley in a manner to effect the starting or the stopping of the operating mechanism for the pattern wheels at the will of the attendant; which means also includes a toggle actuating cam lever S9 which is automatically actuated through link and lever connections 1D by a. cam 'il on a wheel 12 fast on the intermittent-lv movable shaft 4l, so as to effect the stopping and the starting of the said pattern wheel operating mechanism at determined intervals during the brush forming operation. Also located cn the main shaft 39 in co-operative relation to the sleeve or hub of the cam 64 as described in said Patent No. 1,654,655, is a second clutch and brake mechanism 13 which is automatically actuated by a cam 1f! on the wheel 12, through link and lever connections 15 to control the timed operation or" the main shaft and therefore the operation of the boring and tufting devices, as Well as the stopping of such devices while the pattern. wheels continue their rotation and until -they are manually or automatically stopped as previously mentioned.

The brush block supporting tables 49 and 50 have pairs of spaced depending legs 1 each of which is rockably supported on a transverse vertical frame 11, comprising spaced bars, by means of a pivot 1S extending longitudinally of the table; the frame 11 being secured at its ends to upstanding arms which are pivoted on horizontal axes 1B to two vertical slides 8B guided in fixed standards 3i rising from a pair of forwardly extending arms 82 on the cross-bar (See Figs. l, 2 and 5.) Thus the tables are movable longitudinally about the axes 13, transversely about the axes 13, and vertically in the guide standards 8l so as to enable the setting of the block tables in predetermined operative positions in relation tc the cverhanging boring and tufting devices, respectively,

The pivots 1S of the legs 1S of the two tables 4-9 and 5G are pivotally coupled by lateral links 33 which are connected by means of retracting springs es with a cross-rod 55 xed to a stud 3S on one of the end members of the vertical frame 11, which spring connections thus tend to retract the links 83 toward one side of the machine and thereby resiliently to cant the block apanage.

tables on their axes 18. '(See Figs. 1,` 2, 6,.7 and 8.)

The Cams. i8 on the wheel l5 are adapted through suitable connections to: move. the block tables transversely on the axes' iff against the action of the springs 8d; the cams 4l on the wheel et are adapted to move the tablesY vertically, and'v the cams it on the latter wheel. are adapted to move the tables longitudinally on the axes '19',

the various movements. being in. timed relation,

to present the supported brush blocks (B) at determined intervals to the paths; of the boring and. tufting devices.

One feature of my invention resides in the cam actuated connections for moving the block tables back and forth transversely on the axes i8., as follows, reference being had to Figs. l., 2, 5 and 9:

A transverse shaft 8i' is slidably mounted in guide brackets 88 on the forward arms 82 of the cross-bar 43, one end of which shaft 3l hasattached thereto a. strap 89 that passes about a pulley Si? at one side of the frame standard :i1 and` supports a pendant weight 9| tending to retract the shaft 8l. longitudinally in one direction. This shaft has pivoted thereto one end of a parallel link S2 the other end of which has a pin and slot connection with one arm 93 of a bell crank which is fulcrumed, as at 9d, on the crossbar of the main frame, the other arm 95E. of the bell crank being pivoted at Q6 to.` one end of a stabilizing arm 9i having4 a lateral roll 99: which is held in operative relation to the cams 48 by the retractive force of the weight 9|. on the shaft 87|. The opposite end of the arm 97 is bifurcated and bears a roll itil). fitted in a cam slot |13! in a.

horizontal plate |62 which is fastened to the adjacent rearwardly extending arm d2. oi'. the crossbar Hence during the rotation of the cams the roll. 98 and the. adjacent end of the arm @i are radially moved in a manner to swing the bell crank and impart variable longitudinal move ments to the sliding shaft Si in one direction against the action of the weight, andi also to permit the intermittent retractionl of such shaft the opposite or return direction bythe action of the weight. The contour of the cam slot is such as to coordinate the actions of the arm 'i and the bell-crank arm 95 during the varying movements of 'the arm 9,?, and thus ensure the radial movement of the roll 98 in relation to cam wheel.

Loose on the shaft 8l, but movable longitudinally therewith, is a forwardly and downwardly inclined arrn it?) to the outer end of which is pivotally connected the lower end of an upstanding shifter arm |04 having at its upper end a rounded projection |35 which is seated in a corresponding socket I formed in the central expanded portion |01 of a cross-bar |98 connecting the lateral links 83 which couple the legs 16 of the block supporting tab-les 4S and El?. The springs 53d maintain the soclzeted bar lll in constant contact with the projection |05 of the shifter arm iilli, and hence as the shaft 3'! is variously moved lengthwise through its connections with the cams i8 the links 83 are correspondingly iengthwise shifted; thus simultaneously moving the tables on their axes 18 in a manner to present the brush blocks in determined angular relations to the actions of the boring and tufting devices.

in the present instance two sockets |66, one spaced above the other, are formed in the expanded portion of the bar H38 so that the projection m5 on the shifter arm |94 can be seated in either socket, and accordingly enable the variation of the' vertical' position of the frame 'il in relation. to the boring and tuft inserting devices so as toad-apt the block tables for different tuft lengths as the particular style of brush may require. The socketed bar |68 is shown in Fig. '7 in full lines as detachably secured by bolts Hit to thev tops of the links 83. In order to provide for' other vertical variations of the frame 'Vl the socketed bar may be detached and reversely secured to the bottoms of the links 83 as indicated in dotted` lines in Fig. 7, thus enabling further vertical positions of the sockets of the bar wto be had, as occasion may require.

The cam actuated means herein illustrated for moving the block tables i9 and 59 longitudinally on the axes '19, is as follows, reference being had to Figs'. l', 2' and 5:

A horizontal rock-shaft It has its bearings in brackets' on the cross-bar i3 of the main frame adjacent the pattern wheels, which shaft has affixed thereto an arm; H2 having a roll HS which is held in operative relation to the pattern camsY 45. by means of a weighted arm lill on the shaft. Rising from this shaft are two levers i l5, the upper ends of which are connected by links H6 to the upper ends of the upstanding side arms TEU of the frame Stout retracting springs i'i connect the links H6 to rearwardly extending bars HS secured to the standards of the main frame and serve to retract the frame '|'l against the action of the cams l5 on the wheel lift, which cams are of such formation as to effect, in conjunction with the action of the springs lill, the requisite longitudinal movements of the frame il and the block tables to present the blocks in proper relation to the boring and tufting devices.

The cams 4'? on the wheel d4 control the ver-v tical movements of the tables to preserve at all'. times, irrespective of the longitudinal and lateraly movements of the tables, the same distance between the boring and tufting devices .and the portions: of the respective blocks vertically be neath them. These cams il act upon a roll H9: on a lever arrn 52B extending rearwardly from a rock-shaft |2| journaled in brackets |22 on the: base of the main frame. Extending forwardly from the rock shaft |2| are a pair of spaced arms. |273 which are connected by links 2d with a trans verse tie bar |25 slidably mounted at its ends in vertical guides |26 secured to the. standards of the main frame. The tie-bar |25 connects the depending ends of the vertically movable guide bars 8U for the frame 77, and' hence the determined actuation of the lever arm 92B by the cams l effects the requisite vertical movements of the frame Tl for the purpose mentioned. (See Figs. 1, 2 3 and 5.)

The mechanisms just described for longitudinally and vertically moving the tables are substantially the same in construction and operation las those described in the Young Patent No.

664,989, dated January l, 1901.

Simple and efficient means to ensure the accurate positioning of the tables and the blocks thereon in respect to the paths of the boring .and tufting devices at the end of each longitudinal and transverse movement of the tables, is as foliows, reference being had to Figs. 2, 4 and ll):

Pivoted to the block table supporting frame i?, at a point midway between the depending legs 1,6 of the respective tables GLS and 5|), are the depending iegs l2? of a table E23 upon which a flat plate |29 is supported in substantially the same plane as and in parallel relation to the tops of the brush blocks. The plate |29has formed therein rows of perforations |30 corresponding in number, position and angularity with the holes to be bored in the brush block. The pivots of the legs E21 of the table |28 are coupled to the links 63 similarly to the pivots of the legs 16 of the block tables i9 and 50, and hence the three tables are simultaneously and correspondingly moved on their transverse axes by actuation of the links as hereinbefore described.

At the end of each movement of the plate |29 one of the holes therein is in vertical alignment with an Overhanging vertically reciprocating centering pin |31 which is at once snugly entered in the hole preparatory to the boring and tuft setting operations on the blocks, thus ensuring the accurate positioning of the respective blocks in relation to the boring and tuft setting devices. The centering pin |3| depends from a vertical spindle 132 which is slidably mounted in guides |33 on a bracket |34 fixed to the front of the cross-beam 66 of the main frame. The spindle 132 is connected by a pair of links |35 to one arm |36 of a lever which is fulcrumed on the bracket |34. (See Fig. 10.) The other rarm |51 of the lever has a roll |38 which is held (by gravity) in contact with a suitable cam |39 fast on a short shaft |40 mounted below the main shaft in a bracket |41 fixed to the rear of the cross-beam 38. The shaft |40 has fixed thereon a sprocket wheel |62 which is connected with and driven from a similar wheel |43 on the main shaft 39 by a chain |44. The contour of the cam |39 is such that in each rotation thereof the spindle is lowered and raised in timed relation to the centering plate and the block supporting tables.

The boring mechanism herein shown comprises a boring tool |45 at the foot of a vertical spindle |46 which is rotatably and slidably mounted in a guide bracket |41 fixed to the front of the crossbeain S6 of the main frame, such spindle being independently driven by a suitably-supported electric motor |48. The spindle |56 is rotatably connected, as usual, to one arm |49 of a rock lever having its fulcrum in the bracket |41, the other arm of the lever having a roll |56 which is operatively fitted in the groove of a suitable cam 15| fast on the main shaft 39. The contour of the cam groove is such as to effect the vertical oscillation of the lever and the resulting reciprocatio-n of the rotating spindle and its boring tool in timed relation to the block feeding tables. (See Figs. 2, and 1l.)

The ber supply means herein illustrated comprises a magazine |52 which is supported by a bracket |53 on a forward extension |54 of a supplemental frame structure 155 on the cross-beam 38 of the main frame. This magazine is open at one side and is formed at its lower end with a throat portion |56 from which determined quantities of fiber (each quantity suiiicient to form a tuft) are successively removed by a transfer device (T) and thereby delivered to a wisp carrier (C) which, in turn, presents the wisp to the respective actions of co-operatively related tuft forming and setting mechanisms as will be hereinafter described.

In order to ensure the uniform and orderly feeding of the fibers through the throat of the magazine into the transfer device, means are provided for evening the exposed ends of the fibers at the throat, and for pressing the fibers toward and into the transfer device. (See Figs. l2, 13, l5, 16, 17 and 18.)

The fiber evening means comprises a vertically-disposed plate |51 which is arranged at the lower part of the open side of the magazine adjacent the throat so. as to be vibratable against the exposed ends of the fibers. This plate is adjustably connected by means of a rod |58 with the bifurcated lower end of a depending arm |59 which is movable in a path longitudinally of the fibers. 'I'he arm |59 has thereon a bracket 160 which bears a roll |61, the arm being pivoted at its upper end, as at |62, to the front wall of the frame extension |54 which supports the magazine. A retracting spring |63 secured to the bracket |60 and front wall of the extension |54 maintains the roll |61 in contact with a. beveled cam plate |64 on an adjacent pendant arm |65 which is movable toward and from the magazine. Thus the cam |64, in conjunction with the spring |63, actuates the arm |59 in a manner to vibrate the plate |51 against the exposed ends of the fibers in the magazine for the purpose mentioned.

The arm |65 is fixed at its upper end to one end of a rock-shaft |66 having its bearings in a bracket |61 on the extension |54, the other end of the shaft having a depending arm |68 which is resiliently connected to such extension by means of a spring |69. Thus the arm |65 is normally urged toward the throat of the magazine. The shaft |66 has an upstanding arm |10 which is connected by means o-f a rod |1| with a rock-arm |12 included in connections hereinafter described for operating the transfer device. One end of the rod |1| is pivoted to the arm |12 and the opposite end extends loosely through a guide rocker 119 on the arm |10, a cushioning spring |14 being interposed between the rocker and a nut |15 on the projecting threaded end of the rod. The lower end of the arm |65 has fixed thereto a pair of parallel rearwardly extending blades |16 having free vertical edges 11 from the tops of which the upper edges of the blades are inclined downwardly and forwardly, as at |16. The free ends of the blades |16 are movable through slots |19 in the inclined bottom |80 of the magazine by the vibrating arm |55, and hence the vertical edges of the blades in their inward strokes press the lowermost fibers toward the transfer device, and the inclined upper edges of the blades in their return strokes move freely away from the superposed fibers.

The fiber transfer means hereinbefore referred to consists of an oscillatory head of the general character disclosed in my previous Patent No. 1,388,352, dated November 22, 1932, which head in the present machine is rocked in timed relation to the wisp supporting carrier through an arc of 90 between the throat of the magazine and the carrier. The transfer head comprises a segmental member |81 fixed to and supported by radial arms |62 fast on one end of a rock shaft |86 having its bearings in brackets |84 on the lower forward part of the frame structure |55. On the opposite end of the shaft |83 is fixed a sector gear |85 in mesh with a similar gear |86 loose on a stud shaft |81 supported by the frame extension |56. The sector gear |86 has an arm |68 which is connected by a link |89 to the rock- 112 previously referred to. This arm is fast on one end of a transverse rock-shaft |90 having its bearings in brackets |91 on the cross-beam 38 of the main frame. On the opposite end of the shaft |66 is a rearwardly extending arm |92 having a roll |63 operatively fitted in the groove of a cam |94 fast on the main shaft 39, the contour of the groove being such that in an interval in each rotation of the main shaft the connections between the cam and the sector arm |88 are actuated to eifect the oscillation of the transfer head at the throat of the magazine.

The segmental member |8| has a suitably-disposed peripheral slot |95 therein effective to receive a wisp of bers from the throat of the magazine when the segment is at the top of its stroke, and then to carry the wisp down to its position for delivery to the wisp carrier. The segment has pivotally mounted thereon, as at 36, a pair of curved stripper arms |91 which are movable radially in respect to the slot, which arms are swung inward to open the slot for the reception of the wisp at the throat of the maga- Zine, and is subsequently swung outward to deliver the wisp to the wisp carrier. rIhe pivoted ends of the strippers are formed with crank arms |98 connected by a cross-pin |55 extending through an arcuate slot 255 in an expanded arm of a small lever which is pivoted between the crank arms, the other arm 252 of the lever being provided with a roll 253 and being also connected by a spring 264 with one of the segment supporting arms |52. The roll 253 is held by the action of the spring in contact with a stationary cam 255 on an arm 203 having a hub 201| encircling a sleeve E@ and xed thereto. The sleeve is Xed at its ends in the brackets |84 in which the rock shaft |83 is journaled, which shaft extends freely through the sleeve. (Figs. 14 and 18.) The contour of the cam face is such that during each stroke of the segment, the lever 202 is actuated to effect the determined opening and closing movements of the strippers in respect to the wisp receiving slot of the transfer head. A curved guard plate 208 to confine the wisp of fibers in the slot |95 during the delivery stroke of the transfer head is resiliently supported adjacent the periphery of the segment |8|.

In the present instance this plate has a depending pin 252 which is slidable in perforated guide ears 2li! on a forwardly extending bar 2|! bolted to a depending housing 2|2 on the frame structure |55, and which pin is maintained yieldingly in raised position by a suitably-disposed compression spring 2i3. (See Figs. 12, 13 and 14.)

The wisp carrier hereinbefore referred to comprises a slide 2|4 fitted in a guide 2|5 Xed to the housing 2|2 on the frame structure |55, which guide is inclined upwardly andrearwardly from a position adjacent the lower path of a vertically reciprocating plunger 2H included in tuft forming and setting mechanism. The slide 2 i4 has secured thereto a similarly inclined plate member 2|8 terminating in a forwardly extending open wisp supporting structure. This structure comprises a side wall 2|9 extending from the member 2|8 and a side wall 220 parallel with the wall 2|9 and suitably spaced therefrom by means of a cross-piece 22|. The two walls have formed at their rearward ends upstanding jaws 222 with which co-act complementary jaws 223 pivoted on the respective walls, as at 224. The depending portions of the pivoted jaws are jointed, as at 225, to the parallel limbs of a yoke 22S below the forward portion of the cross-piece 22E, which yoke is normally retracted by the action thereagainst of a spring 227 which is seated in a socket 228 in the cross-piece 22|. A retaining pin or screw 22S in the cross-piece of the yoke is encircled by the outer projecting coils of the spring.

By the construction just described it will be seen ithat when the vslide 2|4 is longitudinally reciprocated in the inclined guide 2| 5, the wisp supporting structure with its normally closed jaws is moved in an oblique path intersecting the vertical path of the inserting plunger 2|-'|. As such structure approaches its lowermost position the yoke 225 Aimpinges against .an abutment piece 126 Xed on the forwardly extending bar 2|| on the depending housing 2|2, which yoke is thus moved slightly rearward against the action of the spring in a manner to swing the pivoted jaws 4223 to open position; and in the initial upward movement of the wisp carrier the yoke, leaving the abutment, resumes its normal forward or jaw closing position. (See Figs. 12, 13, 19 and 20.)

The means herein illustrated for reciprocating the wisp carrier includes a. suitable cam 230 on the driven shaft |40, the groove of which cam receives a roll l23| on the shorter arm 233 of a bell crank which Ais pivoted, as at 234, on the beam 38 of the main frame. The other arm 235 of ythe bell crank has jointed thereto a link 235 which is pivotally connected with the slide 214 of the wisp carrier.

When the wisp carrier is in its lowermost position, as seen in Fig. 13, with its jaws open, as previously mentioned, a wisp (F) of bers or bristles is delivered by the transfer head to and upon Ythe spaced side walls 2|9 and 220 of the wisp supporting structure and in the space between the yopen jaws, which jaws in the initial backward movement of the carrier are caused to grasp the wisp andas the movement continues the wisp' is lifted in an inclined plane to a position where it is sustained horizontally and with its midportion intersecting the path of the inserting plunger 2|-|, as seen in Figs. 12 and 22. 'Ih'e plunger 2|'|, which is included in the tuft forming` and inserting mechanism` herein illustrated, is preferably polygonal in cross-section and `is vertically reciprocated in timed :relation tothe block Vfeeding tables. (See Figs. 1, 12, 13,'and 18.) The upper end :of this plunger is fixed to a slide ,23.1 mounted in a vertical guideway 238 formed in the supplemental frame structure |55. The lbody of the plunger 2|'| is slidable in 1ongitudinal grooves in a fixed block 239 having a bifurcate-d lower end 24|) constituting -a staple former through which the plunger is freely movable. The :block 239 yis preferably composed of two mating sections (Figs. and 31) which are Xed in a vertically channeled block 24| (Fig. 26) fastened to .the foot 4of the frame structure |55.

The slide 231 is connected by means of a link 242 f with one arm 243 of a lever which is fulcrumed on vthe .frame structure |55, the other arm 244 being .pivotally connected by means ,of a link 245 to :the plain face of a cam l21116 on the main shaft 3.9.. Thus during the-operation of the main shaft the slide 231v :and therewith the plunger 2|`| are vertically reciprocated, the down stroke of the plunger being such that its lower end enters the opposing hole of the underlying bored brush block.- When the plunger is at the limit of its upper stroke its acting end is within the 'block 239 and above the bifurcated staple former of the latter. The grooved inner `walls -of Athe spaced members of the staple former receive and support the depending legs .of a staple which is formed and `seated between such members., as will presently appear. Y

f Fitted in the vertical guide r238, directly above the bifurcated staple former, is a reciprocative slide 247 to which is allxed, laterally of the -Ver-
